MCQ
Molar heat capacity of water in equilibrium with ice at constant pressure is
- AZero
- ✓Infinity $(\infty )$
- C$40.45\,kJ\,{K^{ - 1}}mo{l^{ - 1}}$
- D$75.48\,J\,{K^{ - 1}}$
✓
Answer
Correct option: B.
Infinity $(\infty )$
(b) ${C_P} = {\left( {\frac{{\delta H}}{{\delta T}}} \right)_P}$, At equilibrium $T$ is constant i.e. $\delta \,T = 0,$ thus ${C_P} = \infty $.
